Description

Die Erfindung betrifft eine Rohrwalze, welche besonders zum Einwalzen von Rohren in Kesselblechen dient, bei denen die Rohrachse nicht senkrecht, sondern geneigt zum Kesselblech steht. Die Erfindung besteht darin, daß an Stelle von konischen Walzen oder von mehreren Ringen von Kugeln, die als Walzkörper dienen, nur ein Ring von verhältnismäßig großen Kugeln angewendetThe invention relates to a pipe roller, which is particularly used for rolling pipes in boiler plates, where the pipe axis is not perpendicular, but inclined to the Boiler plate stands. The invention consists in that instead of conical rollers or of several rings of balls that serve as rolling bodies, only one ring of relative large balls applied

ίο wird, die je für sich in einem Käfig sitzen, der über die Mantelfläche des Körpers der Rohrwalze hinausragt.ίο who will ever sit in a cage for themselves, which protrudes beyond the outer surface of the body of the pipe roller.

In der Zeichnung ist eine solche Rohrwalze im teilweisen Schnitt dargestellt.In the drawing, such a pipe roller is shown in partial section.

Die Rohrwalze besteht aus einem konischen Dorn a, der mittels eines Schaftes b in einer zylindrischen, mit Gewinde versehenen Büchse c geführt ist. Diese Büchse trägt an ihrem äußeren Ende einen Sechskant d, derThe tube roller consists of a conical mandrel a, which is guided by means of a shaft b in a cylindrical, threaded bush c. This sleeve carries at its outer end a hexagon d, the

ao dazu dient, die Büchse in ihre Führungshülse e hineinzuschrauben. Ein Ring/ sitzt fest auf dem Schaft b und verhindert jede Längsverschiebung desselben. Am Schaft b ist außerdem am äußeren Ende ein Vierkant angebracht, auf den ein Windeeisen o. dgl. gesteckt wird. Auf die Führungshülse e ist außerdem ein Ring m aufgeschoben, der mittels der Schraube? festgehalten wird. In dem unteren Ende der Hülse e sind öffnungen angeordnet, in welchen harte Stahlkugeln h liegen, die sich gegen den Dorn α stützen, wobei die öffnungen in der Hülse so ausgebildet sind, daß die Kugeln nicht nach außen herausfallen können. Je nach Größe der Walze werden fünf oder sieben Kugeln angeordnet, vorteilhafterweise nimmt man dabei eine ungerade Zahl.ao serves to screw the bushing into its guide sleeve e . A ring / sits firmly on the shaft b and prevents any longitudinal displacement of the same. A square is also attached to the outer end of the shaft b, onto which a winder or the like is inserted. A ring m is also pushed onto the guide sleeve e , which by means of the screw? is being held. In the lower end of the sleeve e there are openings in which there are hard steel balls h which are supported against the mandrel α , the openings in the sleeve being designed so that the balls cannot fall outwards. Depending on the size of the roller, five or seven balls are arranged, advantageously using an odd number.

In der Zeichnung sind die Käfige η der Kugeln nach außen ausgebaucht, so daß das Rohr k in einer entsprechenden Neigung schräg zur Rohrwalzenachse stehen kann. Der Grad dieser Neigung hängt ab lediglich von dem Betrage, um welchen die Kugeln aus der Mantelfläche des eigentlichen Rohrwalzenkörpers herausragen können, und dieser Betrag ist um so größer, je weiter sich der Kugelkäfig aus der Mantelfläche erhebt.In the drawing, the cages η of the balls are bulged outwards so that the tube k can be inclined at a corresponding inclination to the tube roll axis. The degree of this inclination depends only on the amount by which the balls can protrude from the outer surface of the actual tubular roller body, and this amount is greater, the further the ball cage rises from the outer surface.
